At present, mainstream unmanned aerial vehicle launching systems of underwater vehicles are all based on the principle of dry launching.
One method of dry launch drones requires that the underwater vehicle be raised vertically out of the water, creating a channel that allows the drone to launch vertically. In actual operation, sea waves have great influence on the vertical posture of the underwater vehicle, the shaking of the underwater vehicle can influence the stability of unmanned aerial vehicle emission, and the unmanned aerial vehicle can be damaged very easily or fails to emit when being in contact with seawater.
